Yes. Imagine sand stone. It is composed of sand. Sand is ground rocks. Pressure and time create sand stone.
Aggregate is the gravel or stone in the concrete. It is what gives concrete it's strength. Think of the aggregate as the bricks of a wall and the concrete and sand as the mortar.

mortar are mixing by sand & cement and concrete is mixing by cement, sand & stone
Sixty specimens each were made of type III and type IV dental stone (Excalibur). Compressive strength of both types of stones significantly (P<.001).
The sand acts the same as the rocks & gravel in concrete, they add strength, volume and keep the chalky grout product from crushing. No sanded groud should be used on polished stone with very narrow groutlines, but sand must be added for wider grout joints or the product will lack volume, be chalky and crack.

Advantages: high crushing efficiency and little powder. Disadvantages: the shape of the particle is not good; the liner is abraded hardly. http://www.sbmchina.com
Shear strength of fine sand is determined by the angularity of the sand particles, the grading of the sand. These two features governs the critical state shear strength parameters of the sand. Density, however, dictates the peak shear strength of the sand. i.e. the denser the sand, the higher the peak shear strength. But the critical shear strength remain the same. The denser the sand, the lower the void ratio. Shear strength of fine sand is determined by the angularity of the sand particles, the grading of the sand.

Cement is hydrated limestone. Concrete is cement, stone and sand. Sometimes fiberglass fibers are added to increase strength.
Crushed stone density is variable ranging from 2.4 - 2.7 Metric Tons per cubic Meter depending on the type of stone, the stone crushing machinery, and how the crushed stone is sorted after crushing.
It is the crushing/destruction of a stone in the bladder.
